I just wanted to know the words to the song in Mononoke Hime, so I transtaled them here, enjoy!

はりつめた弓の ふるえる弦よ

haritsumeta yumi no furueru tsuru yo

The trembling bowstring of a drawn bow

月の光りにざわめく おまえの心

tsuki no hikari ni zawameku omae no kokoro

Pounding in the moonlight, your heart

とぎすまされた 刃の美し

togisumasareta yaiba no utsukushi

The beauty of a sharpened sword edge

そのきっさきによく似た そなたの横顔

sono kissaki ni yoku nita sonata no yokogao

Your profile looks much like that sword point

悲しみと怒りにひそむ まことの心を

kanashimi to ikari ni hisomu makoto no kokoro o

Lurking in the sadness and anger, knowing the sincere heart

知るは 森の精

shiru wa mores no sei

Are the spirits of the forest,

もののけ達だけ

mononoke tachi dake

only the spirits,

もののけ達だけ

mononoke tachi dake

only the spirits...
